Ok, well, considering you did give a lot of great info with this, let me
ask a question which I have been wondering about the STAT.

What is N and W?
ie:

dlmud 13303 0.0 0.0 1960 0 ? SW Sep13 0:00 [bpstart]
dlmud 13318 0.0 0.9 13700 2416 ? SN Sep13 0:10 dlm 3779 copyover
dlmud 15663 0.0 0.0 0 0 ? ZN Sep13 0:00 [dlm <defunct>]

In this example, I will assume that the S is for Sleeping, but what is the N and W.
I would think that the N is for Nice, but am unsure.

Thank you
